Multiple WAN (MWAN)

The Multiple WAN (MWAN) feature allows you to configure all but one of the appliance's interfaces for WAN network routing (one interface must remain configured for the LAN zone for local administration). All of the WAN interfaces can be probed using the SNWL Global Responder host.

Network Interfaces

The Network > Interfaces page allows more than two WAN interfaces to be configured for routing. It is possible to configure WAN interfaces in the Network > Interfaces page, but not include them in the Network > Failover & LB page. Only the Primary WAN Ethernet Interface is required to be part of the LB group whenever LB has been enabled. Any WAN interface that does not belong to the LB group is not included in the LB function, but performs normal WAN routing functions.

NOTE: A virtual WAN interface may belong to the LB group. However, prior to using within the LB group, please ensure that the virtual WAN network is fully routable like that of a physical WAN. A default gateway IP is required on the WAN interface if any destination is required to be reached via the WAN interface that is not part of the WAN subnet IP address space, regardless whether a default route is received dynamically from a routing protocol of a peer device on the WAN subnet.
